研究目的
Comparing different architectural approaches for 5G networks (C-RAN and DA-RAN) in terms of techno-economical aspects and evaluating the introduction of TWDM PON to reduce costs.
研究成果
DA-RAN architecture offers economic and energy savings over C-RAN, with better traffic distribution in the optical fronthaul network. TWDM PON can reduce costs in the local loop under certain conditions, providing up to 10% savings when strategically implemented.
研究不足
The study does not consider the installation of new infrastructure for antennas, assuming the use of existing sites. The analysis is limited to a specific geographical area and may not be universally applicable.
1：Experimental Design and Method Selection:
The study involves network planning simulations for C-RAN and DA-RAN architectures, focusing on cost, energy consumption, and efficiency.
2：Sample Selection and Data Sources:
The simulations are based on a metropolitan area network in northern Italy, serving over 1400 antenna sites and 300,000 users.
3：List of Experimental Equipment and Materials:
Includes point-to-point fiber connections, TWDM PON, grey and colored transceivers, ROADMs, and MPLS-TP fabric.
4：Experimental Procedures and Operational Workflow:
The process involves converting user traffic into fronthauling traffic, calculating traffic matrices, sizing network elements, and routing traffic with protection.
5：Data Analysis Methods:
The analysis includes cost comparison, energy consumption evaluation, and network dimensioning parameters.
